EN1092 ASTM A182 F53 / UNS S32750 Super Duplex 2507 Plate / Flat Flange

Super Duplex 2507 Flange ASTM A182 F53 RF Plate Flange EN1092-1 Type 01 Flange

A plate or flat flange is a type of flange that is flat and typically circular, designed to be welded or bolted to pipes or other components to form a secure connection. Materials under ASTM A182 specification are specifically engineered for high-pressure, high-temperature applications. F53 offers exceptional properties to its super duplex stainless steel composition. The alloying elements in F53 also make it highly resistant to corrosion, especially in chlorinated environments, making it suitable for use in chemical and marine applications.

Manufacturing Process: Flat flanges are often produced through processes like forging, rolling, or machining from larger plates, ensuring they meet the required specifications and standards.

Compatibility Challenges

• EN 1092-1 vs. ASME Standards:
  EN 1092-1 flanges have different dimensions (e.g., bolt hole spacing, thickness) compared to ASME B16.5/B16.47. Ensure the flange is manufactured to EN 1092-1 dimensions if required for system compatibility.

• Material Cross-Reference:

  • EN 1.4410 (X2CrNiMoN25-7-4): European equivalent of ASTM A182 F53/S32750.

  • If the flange must comply with EN 1092-1 material standards, confirm the use of EN 1.4410 instead of ASTM A182 F53.

Application

• Oil and gas exploration: Subsea pipelines, Christmas trees, manifolds.
• Chemical processing plants:HCl, H₂S, and chloride-rich environments.
• Marine applications: onshore & offshore engineering.
• Power generation:Flue gas desulfurization (FGD) systems.
• Desalination Plants: Seawater reverse osmosis systems.
